COOLING SYSTEM FORl GAS-ENGINES.

Application filed March 24. 1919.

lie it known that we. llonnn ll. Jl's'rxtu and l'lnnlxn J. (Tlhuirx.eitizeus ot' the l'nited States. residing at Pasadena, in the munt)Y ot'Los Xngeles and State ol' (Talit'ornia. have invented new and usefullinprorenients iu ('ooling Systems for tiasllngines. ol' whieh thefollowing is a speellieation.

(hir ohjeet is to` make an air eooling s \'S- tem for ,Las engines. andour invention eousista otA the novel features herein shown. de Serihedand elaiuied.

Figure l is a side elevation parti)r in sie tion ot' a gas engineprovided with an air eooliug .system in aeeordanee with the prineiplesot' our invention.

Fig. is a fragmentary front elevation of the engine and eooling systemas seen looking in the direetion indieated by the arrow E?. in Fig. l..

Fig. 3 is a fragmentary rear elevation partly in section as seen lookingin the direc'A tion indicated by the arrow 3 in Fig. l.

Fig. -l is a fra rmentary cross section on the line 4--4 of l.

The water jacket 1 is constructed to malte a large ehalnher 2 ahove theheads of the er1- gine cylinders 3, and the inlet l from the top o." theradiator to the ehamher t?. is vertical, there being an opening 5through the easinr leading horizontally into the ehamber 2. i flange (ifits against the easing in position to rover, the opening 5 and issecured in plaee h v bolts 7. ltlne openings 8 are t'ornied through thecentral portion of the ange 7 in line withthe opening An opening 9 isformed through the rear end of the casing in line `With the opening 5, aHarige, 10 tits against the easing to cover the opening 9 and `has tineholes l1 in line with the flue holes 8, and a spout 12 extends outwardlyfrom the flange-1t) around the openings' 11. Air tlues 13 are serewedinto the openings 11 and extend through the charnher i? and through theopenings S, and the forward ends of the flues are expanded and tightenedinto the openings'. A flexible pipe it connects the spout l2 to theintake Specification o Letters Patent.

lf of the earhureter lo'. A funnel 1T is seeuredtto the flange t3 andextendsy forwardly in position to reet-ire the air whieh passes throughthe radiator l5'.

The .surtion of the engine will draw air through the pipe H. through thelines 1S, and through the funnel 1T. and the eold air passing throughthe lines ll will eool the water in the ehamher :3. aml the eooling ofthe water will warm the air and the Warm air will pass through theearbureter 16 thereinv improving the aetion of theearhureter and theaetion ot' the engine. and at the same time etieetnallr eooling the hotwater at the top of the engine eylinders and avoiding the neeessity otlthe usual fan.

Various ehanges may be made without de parting t'roln the spirit of ourinvention as elainied.

ll'e elaim:

l. eooliug system for gas engines rontprisiug air fines mounted toextend through the water ehainber. and a eonneetion between thediseharge ends` ot' the air ilues and a Carhureter. so that the actionof the engine will draw air through the tlues to eool the water and warmtht` air.

2. Cooling system for multiple cylinder g in Combination with a gasengine having a cooling 'attr jaeket eoinniou to all the ovlinders. .ofair tlues mounted through an upper portion of the water jai-liet andabove the cylinder heads longitudinally otthe Cylinders. a funnel at theforward end of the air tlue t'or direeting air thereinto and a eonduit`for eonneeting the rearward end of the air tlues with a carburetor ofthe engine.

3. A eoolingsystem for gas engines having a eooling water jaelt'et. airfines mounted through the. water jacket above the eylinder having aforward end open to the` in- How of air and a ronduit for connecting arearward end of the air fines with a ear-V bureter of the engine. l

ln testimony whereof we have signed our names to this speeil'ieation.
